How to wind an automatic mechanical watch (less exercise)

According to the transmission ratio, the handle turns 18 times, which can meet the requirement of 36 hours of watch life. Because everyone's winding strength is different, and the friction of waterproof apron on the head of the handle is also different.

Therefore, when the spring is completely relaxed, it is best to rotate the handle for more than 20 times. All the clockwork can last for 40 hours in theory (except for special watches), but the accuracy of the watch after 24 hours cannot be guaranteed.

When the hairspring is at rest, a certain moment is applied to the spring, that is, winding. At this time, the watch does not shake, but the hairspring can swing automatically, indicating that this watch has high sensitivity. If you need to shake the watch to go, it means that the sensitivity of the watch is low. This phenomenon is generally caused by the excessive position difference of the balance wheel.

Precautions for automatic mechanical watches:

1, wear it normally to avoid vibration, so that you can continue to wind up and run normally (the wearer may be slow when the activity is small, which is normal. When using it for the first time, please turn the handle for 20-30 times to make the spring tighten initially. Although the watch is shockproof, it is easy to break the tip of the pendulum shaft or the journal of the gear train under the strong external impact, and it will also make the fast and slow hands vibrate, which will affect the running time.

2. Preventing Magnetization Although watches are made of nonmagnetic materials that are not easy to magnetize, they are greatly influenced by magnetic fields when walking, such as the magnetic buttons on televisions, radio speakers, backpacks or purses.

3, the watch is waterproof, try not to bring a watch to swim and wash clothes. Once it rains or gets wet, you can't pull out the watch handle to adjust the watch, but dry it immediately. Because the handle of the watch is prominent, you should try to avoid bumping. Also, pay attention to the gap between the handle and the shell. Too small will affect the operation, too large will affect the waterproof performance, unsightly.

4, watch cleaning Generally speaking, 3 to 5 years of sludge cleaning is determined by the following factors: ① the sealing problem of the watch; (2) Wear degree of watches; ③ Quartz watch can prolong the oil washing cycle; ④ Men's watches or pocket watches can have a relatively thin oil washing cycle.

If the watch is not used for a long time and is not put in the suitcase with mothballs and health balls, the watch oil will deteriorate, and the watch machine will be wound or worn from time to time every month to ensure the flexibility of internal activities.
